OBERER, 0F PORTLAND, OREGON, ASSIGNOR BY DIRECT AND MESNE ASSIGNMENTS, T0 IRONCLAD' SILO COMPANY, OF PORTLAND, OREGON, A CORPORA- TION OF OREGON. J

To all whom it may concern:

Be it known that I, FREDOLIEN J. OBERER, a citizen of the United States, and a resident of the city of Portland, county of Multnomah, State of Oregon, have invented a certain new and useful Improvement in Bands for Circular Containers, of which'the following is a specification.

My invention relates to the hoops or bands of circular containers built of staves, and especially relates to silos. Since the latter are built with a flat surface at the front side for the doors, and the bands must inelude flat bars at this part, it is found convenient to make the bands of rods bent around the silo body and to secure the ends of the rods to said flat bars by means permitting the relative shortening and lengthening of the rod bands, so as to tighten and loosen the same.

My invention has for its ob ect the providing of improved simple, eflicient and con venient connecting elements between the ends of said flat bars and said bands; also to provide bands or hoops including straight and flat members for the front or the door side of the silo.

To this end my invention consist of a double flanged bar preferably made of two angle bars, and swivel lugs 'pivotally secured between the flanges and at the ends of said bar so as to be rotatable on vertical axes. The swivel lugs are each made with a horizontally extending eye to receive one end of a band. The extremities of the latter are threaded, and nuts are placed thereon for securing said ends against slipping out of the eyes of the lugs and also for relatively lengthening and shortening the band. The threading of the extremities of the band and the nuts thereon, however, are to be understood as merely representing means for relatively shortening and lengthening the band. By making the lugs rotatable they better accommodate the ends of the band, and fa cilitate the insertion of the ends of the band; for the eyes may be. alined with the bandends to be inserted therein. This arrange- .ment also permits the band to so adjust itself as to properly encircle the circular stave body, and thus hold the staves firmly together.

In the accompanying drawings: Figure 1 shows portions of the stave body of the silo adjacent the door, part of the frame of Specification of Letters Patent.

which is shown; this view illustrates the general construction and operation of my improved bands; Fig. 2 is a top view of one of the swivel lugs included'in my device; this view showing the related end of the band as inserted in said swivel lug and having a nut threaded on its extremity by the adjustment of which the band is relatively shortened and lengthened; and Fig. 3 is a sectional elevation of the right end of the double flanged bar in which the swivel lugs are trunnioned and shows the details of construction preferably employed by me in carrying my invention into practice.

it represents a band made in the form of a rod encircling the stave body. The ends it of the rod hare threaded. Said ends are inserted through the eyes of the swivel lugs f and after having been so inserted nuts 2' are placed on the threaded ends to prevent them from pulling out, and also to relatively shorten and lengthen the band, and thereby tighten and loosen the same. In practice one end of the bandit is first inserted in one of the swivel lugs f, and the other end of the band is then brought around the body of the silo and inserted in the swivel lug at the opposite end of the bar 0. The difliculty arose in the last mentio-ned act, in the devices heretofore employed. The eye through which the end of the band had to be brought could not be alined properly so as to accommodate the in-' a said flanges, said swivel lugs made with eyes, a band having its ends inserted through the eyes of saidswivel lugs, and means for relatively shortening and lengthening the band. 7 I V 2.
